PUSH LOCK SWITCH

PROBLEM TO BE SOLVED: To provide a push lock switch that can be miniaturized as its length can be reduced in the direction of sliding movement. SOLUTION: The push lock switch includes: a first and a second switch case 10, 210; an operator 110 slidably housed in the first and second switch case 10, 210; a snap spring 190 that snaps the operator 110 in the direction A of sliding movement; a switch mechanism 50 where a contact is opened and closed by the sliding movement of the operator 110; and a lock mechanism 150 for locking the operator 110 in a locked position to which it is pressed and moved against the snapping force of the snap spring 190 and for automatically returning the operator to an unlocked position as it is pressed again. An area S3 in which to install the snap spring 190 and an area S2 in which to install the lock mechanism 150 are juxtaposed in the direction A of sliding movement, and the areas S3, S2 and an area S1 in which to install the switch mechanism 50 are arranged in parallel and in opposite positions across the direction A of sliding movement.
